Hi, I have recently bought a CLAE 10hp engine made in Australia and I'm hoping to find some information on it. Unlike the normal F10 engine this is an overhead valve version which I have not seen before or heard of. If there is anyone that can shed some light it would be much appreciated. pics attached.

Hi Mangrove, I have used the old side valve CLAE twins in years gone by but haven't seen the OHV version before. CLAE also did marine conversions of Holden motors and it could be that they have used Holden parts (eg pistons, valves, perhaps even push rods etc) in the OHV twin but that's only my guess. It appears the change will not have rasied the centre of gravity of the twin by much?

According to my research there is no such engine! Just goes to show, you can't believe everything you read! Certainly looks to be the usual F10, but with the addition of an ohv cylinder head. Could it have been an experiment? I have seen F10 ads into the 1960's and all are side valve. The only advertised ohv model was the 4hp P4. The earliest reference I have found for the F10 is 1940. Certainly no Holden parts in that era.

Matt & Ron, Yes I am one of the Oatley Derwents. I think I'm the only one (silly enough) who still has an OME running. Should I ask how you know the family? I note there is another (7HP this time) Simplex on E-bay now. Cheers

Hi Tim,Eric, Matt and Laurie,if I may say hello. A new one on me this OHV CLAE. Todd Vidgen may know something . To Laurie -I am ex Connells Point and a few years ago purchased a launch with an F6 in it from the Woronora River 'new out of a crate in the 90's'. Goes beautifully .Do you know it ? Also I have a Simplex 6 hp on Ebay at the moment. Cheers

Hi Matt, sorry you missed out on it, but I already have the 4 Bantam and an F6 , so I had to have the bigger one. Also on the g'box top it says it is a bulldog clutch type. I might be wrong but if the head gear wasn't on, is it the same as an ordinary F10 or is it smaller. Cheers Tim.

Laurie i am from Oatley, now living in Arncliffe but my dad still lives there, growing up around the oyster leases was great, i went to school with Micheal Derwent and played a lot of footy with Glen. We put our Stuart Turner powered putter in at Moores reserve, and flip a coin to see if we go up or down the river. If there is enough water we always check out the welfare of a very old launch that is moored at Neverfail bay, A Simplex or Clae twin would be just right for this launch. Regards , Matt and Ron

Thanks Matt, I'm not sure where Glen is these days but last I heard Michael was managing a cotton farm up Barraba way. His folks have both passed away. It's good to see someone with a Stuart Turner who has courage enough to flip a coin rather than just drive against the current on the outward journey and then drift back! That launch at Neverfail is now over 100 yrs old and was built in Oatley for my great grandfather. It's design comes from the sailing skiffs of the day amd for many year it had a 4 cyl WWII jeep engine with the Jeep gearbox. It was restored about 15 yrs ago by cousin Ron. My 18' batten built boat is also moored there(the cat between then is my son's) and I have a GRP boat with twin Blaxland (about to receive a twin Simplex). Cheers, Laurie.

The often maligned Stuart Turner P55 that powers the RubyToo was only beaten across the line by two Blaxland engined boats at the last challenge at Davistown. Those boats being skippered by Boyd Myers and Allan Graham where running quite hot engines. We have also come across Botany Bay into a stinker sou-easter with water over the top of the floor boards and she didnt miss a beat. But the mobile phone is always on the boat. Matt and Ron

Matt, There's can be no argument that the Ruby Too is a fine looking boat and given the P 55 is rated as producing more Shetlands than the Blaxlands I would expect it to perform well against the standard 5/7 twins. From my younger days I can say that the Stuart Turner was well respected but, being two strokes, they obviously need respect, especially when hot (just like a woman or a chain saw). As for the trip across Botany Bay with lots of water on board... Some blokes will do anything to avoid hot starts!.

I can't say that I know about the Woronora boat/motor.. but I haven't really got around that much in the local OME scene (apart from those the family used to have).

I do not know the full details of my GRP boat's lineage. I bought it 20 years ago from a bloke who said it was from a Halvorsen's work boat mould. He called it an American dory but I think the mould may have been made by tinkering with any traditional shapes.. I have seen two others - one on Trading Post with an Outboard transom and another was a photo of a boat in Sydney Harbour. The person I was talking to did not have any details of the pic or the boat. My boat loves to throw spray over us in Botany Bay in any breeze but rarely takes any actual water on board. Regards.

Hi Laurie, the reason I asked about your boat is that we (a few mates) have built 5 of the ones in the pics attached and one had a blaxland twin in it that was sold and we have never seen it again, so I thought it may have been it. Not so. We took a mould of an old boat and had some fun. One is on the Gippland lakes, two are nearly finished and the other was sold to a friend of a freind and haven't heard of it. Cheers Tim.

I would like to put a dynastart system onto my twin cylinder Blaxland can someone advise please equipment needed and diagram, can one get brackets for the starter or need to make them , Hope someone can assist email me .

I own a complete and running F10 - my guess is the ohv engine is a 1 off prototype, never sold but somehow escaped the factory. This has happened with stationary engines too.
